The tank was running in my 12G before and I just tranfered everything over to a larger tank. (Then I decided to still use the 12G) If you look at my sig. you will see the rest of what is in my tank. I do have live rock, ~29 lbs. For corals I have Alveopora, Zoanthids, Montipora, Frogspawn, Cynaria Brain, Feather Dusters, 2 Kenya Trees, and Blue Mushrooms. All of that is thriving.
